'Weather bombs' could present deep details of Earth interiors
These storms produce very strong winds that cause the ocean to swell, generating powerful waves.
New Delhi: A team of Japanese scientists, for the first time, detected a small, deep-Earth, intense storm off the coast of Greenland. These waves can reveal a lot about the mysteries of Earth's interior.
The latest study shows that the tremors are caused by seismic waves dubbed as S waves which are detectable anywhere in the world. A "weather bomb" is an extratropical (outside of the tropical zone) storm in which the central pressure intensifies rapidly.
These storms produce very strong winds that cause the ocean to swell, generating powerful waves. Some of the wave energy from these storms interacts with the seafloor, causing wave-generated seismic activity, according to Live Science.
The S waves can easily penetrate the Earth's surface and can be observed at faraway seismic stations, scientists said. In the study published in Science, scientists reveal that they found S waves having a velocity of 20 to 22.2 kilometers per second in the North Atlantic Ocean using seismic sensors.
This breakthrough discovery could help seismologists and other experts to have a clearer picture of the inner workings of the planet.
